//but jim, surely you can see that he would not even have been there had he not been a lowlife criminal. //
Can't you see that it is completely irrelevant? I agree that he should never have been portrayed as an angel, as he wad a previous offender, but regardless of why he was there, he should not have been treated as he was.
It's like saying that if Rodney King wasn't drunk driving, he wouldn't have been beaten up by those traffic cops in 1992.
Or, even worse, if a rape victim wasn't wearing a short skirt, she wouldn't have been raped.
Victim blaming is just not right.
